Ring Automotive - RSC804 Smart Car Battery Charger 6V 12V 4A, Black

This is a very useful and easy to use device, I have used it twice so far to boost the agm stop/start battery in my VW Diesel Golf which spends a few weeks at a time without being used. When attached the display shows current battery voltage status on an LCD backlight display, and charging status with a series of 5 flashing bars which become solid as charging ensues. Last time I charged it went from 12.2V to fully charged 14.7V in approx 6 hours. It can also be used as a trickle charger. I liked the compact size, Hanging hook, and in my case cable lengths although the car is adjacent to wall socket. Seems like a good product at reasonable price.

I have 3 of these, no trouble with any of them. They work well for my motorcycles which are attached to them while garages and also for the car or van if the lights were left on.Great product.

Great value for money. Waterproof rated, easy to use.Would have liked a waterproof battery connector too as I have to take the bike seat off to charge the battery

Smart charger value for money

I read reviews thinking this would be a decent accurate charger. My view is that it is not.The unit arrived and after opening is where things started to disappoint.The quality is not great. The wires are thin guage. The included tender has no terminal covers either so the SAE is exposed.On connecting and switching on it displayed battery voltage. You then need press button to cycle charge . The digits for voltage is clear however they mode selection is so small you need squint to see it. Once more selected the only way to cancel it was disconnect battery. And then cycle the options again squinting at the feeble display.The unit looked like it was charging hoeing me output voltages which I thought was a nice touch on the backlighted screen. It then said full so job done.Well no. It really wasn't done at all so it lied.I'm not happy that it's not sensitive enough to fully charge a battery. This may well be adequate for most people but not for meOn mains power disconnect it stops the charge cycle and you then need select mode to start it up again. I'm unsure if there is a diode within the circuit to prevent battery drain.There is a notable sound from the unit in use.Overall I think the unit could be better made and especially the user display made clearer. Who wants to fumble around for spectacles to then squint on a small display screen?I'll keep you Noco chargers that actually fully charge batteries. Get what you pay for I guess

Bought as a motorcycle battery charger.. does the job well, not as fussy as some more expensive models, easy to use switching between car/motorcycle 6v and 12v, even has summer/winter settings if used as trickle charge. Good product

A nice compact smart charger. The ring eyes to connect permanently to your battery, are far larger than the picture would indicate. The plug connector on the end, though, is very tight to connect to the charger. I was confused the 1st time to see voltage rise to over 13V, but it appears that this must be the voltage applied to the battery. It does imply that you can leave it charging till "FULL" is shown, but no indication about how long this might take, or whether it is OK to leave it connected for longer. I left mine connected over night, and there didn't appear to be an issue. Proper instructions would help a lot. Can I for example, leave the charger connected to the battery, but not to the mains supply?

Great bit of kit. Easy to use comes with interchangeablecrocodile clip lead and a lead to attach straight onto the battery terminals both attach to end of main cable so you can switch between the two. Or just stick with the one you prefer. Compact unit with handy hook on the back that folds out so you can hang unit from bonnet/ hood catch. Sealed unit so is weather proof. Digital display let's you know charge level of car battery. I would highly recommend.
